No, water will make it worse. All it does is cool the core and bring atoms closer to each other, increasing the fission events from immediate release neutrons.

Keep in mind the balanced core uses both immediate and delayed release neutrons. Meaning the fission blob grows at the slow rate of delayed release neutrons.

But cool it and the thing flashes over violently. Expands as far as the fuel will allow and then trips over itself and contracts. This action rings until the sudden in flux of cooling material is resolved.

Lead absorbs neutrons well, which is ideal for nuclear suppression.

The more heat you pull from the reaction, the more violent the reaction becomes. It's a balance of nature in a run away situation.

As you pull more heat, more radiation is emitted all around. Making the situation even worse and possibly explosive.

I don't disagree with what you are saying, but certainly coolant has been dumped on hot corium before without massive steam explosions and rapid physical expansion, TMI was melted, they cooled with water... Same as Ignalina. By what you are positing, the ECCS injection over corium would cause the volume to expand so much and rapidly that it would burst the containment vessel and this did not happen at TMI nor the BWRs that got away on nuclear submarines and the icebreaker Lenin (actual melt). It makes it worse to be sure, but it's not like trying to put out a fire with jet fuel.

i cannot concure.. 'corium', is that wonderful word we use for the unknown conversion of properties that were not 'thought about'.... that being, 'corium' is an unstable and unknown element that should not be released into the environment without superflouse study....

if they had found an answer.. really?.. should that have been done in 1950 or 2011?......

was the 'race so important' to boil the water to make plutonium?...... really?

Sounding more and more like the Edgar Cayce prophecy of "The greater part of Japan will go into the sea" is shaping up to be a mass exodus. Not necessarily that the land mass will drop into the sea, but that the greater part of Japan's population will take to the seas in boats or planes to get the hell out of there!

In his book, "Between Two Ages," Brzezinski wrote: "The technetronic era involves the gradual appearance of a more controlled society. Such a society would be dominated by an elite, unrestrained by traditional values."

How much has temp gone up . As too hard to read link . If its 5 degrees or more ,serious damage for all plants and critters in the effected zone . No more fish in that part of the world. Why do you think all the dolphins bugged out a month or so ago.

The reason that doom has not manifested since 8/23/11 is due to the fact that our galactic brothers and sisters, as well as Agarthans below (and Heather Ann Tucci-Jarraf) who all love us very much, are now allowed to intervene on our behalf; more so than just actions such as shutting down nukes. We can be quite confident that non-local emergency teams tend to every situation that has the potential to be an ELE, e.g., the asteroid explosion over Russia. What Dr. Steven Greer is about to disclose, and to a slightly lesser extent GW Hardin's recent talks, will back up this statement.
